I love posting resources that I think are useful for nonprofit leaders trying to up their communications game. Here's a very useful discussion of color and its meaning for brands. The symbolic association of color is obvious once you hear it articulated, less so until you do.
I was at the North Star Fund in New York last week and was so delighted to see how their brand has evolved. They've chosen a strong red for their core color that's just shy of fire engine (or old Soviet Union poster red) without going too pink which would be too soft for an organization at the vanguard of social change. A really smart choice!
